Highly Temperature Sensitive Delayed Luminescence from Gd2O2S:Eu
Abstract
The highly temperature sensitive delayed luminescence from the well-known phosphor Gd2O2S:Eu (1%) was characterized for excitation at 365 nm of 1 second duration. The main component of the luminescence decay time ranged from 1.87 to 0.07 s from 24.5 °C to 55.1 C, exhibiting a sensitivity of 11% /°C. The amplitude also showed a marked temperature dependence increase of 7% /°C. A parameter Q(T), defined as the ratio of the decay constant to amplitude, has a sensitivity determined as 18%°C. Four measurements of a shorter component also showed pronounced temperature dependence, ranging from 0.14 s at 24.5 to 0.02 s at 43.5 °C.
